When inverting, the stances also have a range, with a smaller separation between their opposites. In simplest terms, the feet switch back and forth every 90 degrees relative to the direction of the flip in a skill. This thinking is only applicable to singular and sequential landings, however. When dealing with unified landings, landings on both feet simultaneously, the extreme range of a landing is generally accepted. In simplest terms, this means that unified landings in complete are in a backside position, hypers are inside, mega is frontside, and semis land in the outside position. It is pretty rare for people to acknowledge a mega when landing forward on both feet, like from a front flip, but technically that’s what it is. The unified semi landing, or outside position, is often accepted as a higher rotation complete, particularly when higher rotations are attempted, such as triple and quadruple twisting. In short, mega and semi unified landings don’t even exist to many people, despite being technically existent.
Singular and sequential landings can be viewed as a little more loosely defined. In ideal terms, they are defined by leg and rotation, however, by altering only the landing leg without rotating further, a short landing can be achieved, with its own set of properties and options. A short complete landing is the position most typical to a -round variation and the lotus swing. The short hyper, or backside landing on the inside kicking leg, allows for the true backswing necessary for a Kroc, and so on. (For more information on invert landings: Beginner // Advanced) Notice that if a range is not accepted, and landings are defined at exact positions, 8 landings, not 4, are necessary to cover the possibilities, and the system becomes increasingly complicated.
Accepting that landings are ranges, or quadrants, there are 2 unused quadrants for each foot, with the mid point (45 degree mark) of each creating the logical separation for an over-rotation of one stance to the under-rotation of the opposite. For example, if extreme end of a complete landing is thought of as backside with the outside kicking foot facing backward, then the short-mega range begins 90 degrees past that, facing perpendicular to the direction of flip, in an inside position. The division between complete and mega in this instance would logically be at the 45 degree mark between the two ranges, because by passing it in either direction, you are closer to one stance than the other. The point of this distinction is not to advocate lax standards at all, but to be used as an objective gauge when analyzing a trick. Landing between the minimum and maximum ranges for a landing stance should indicate that more work needs to be done to avoid ambiguity.
In the diagram above, the purple feet indicate the base leg for singular transition, and the first landing leg in sequential landings. The large feet indicate the relative position for unified landings, and the smaller feet indicate the short landing range. Next to each purple foot, a common swingthrough twisting axis is listed.
